DELMER C. PORTER AND JOSEPH ERVVIN, OF CEDAR RAPIDS, IOVA.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed October 3,1904. Serial No. 227,064.

To all whom, t may concern:

Be it known that we, DELMER C. PORTER and JOSEPH ERWIN, citizens of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Steam-Heated Collar-Shaper, of which the following is a specification.

This invention relates generally to laundrymachines, and particularly to a device for shaping collars after they have been ironed.

The object of the invention is to provide an exceedingly cheap and simple device for shaping collars so constructed that it is only necessary to feed the collars to the Shaper, each succeeding collar serving to force the other collars through the Shaper, each collar remaining a sufficient time to be and shaped.

The invention consists, essentially, of a tube having a smooth interior and a grooved exterior and provided with a heating-coil held in the grooves, the collars being fed into the upper end of said tube and forced down and out through the lower end.

The invention consists, also, in providing vertical notches in the upper end of the tube, so the collars can be ushed down by the lingers below the top ofJ the tube.

The invention also consists in certain details of construction hereinafter fully described, and pointed out in the claims.

In the drawings forming apart of this speciiication, Figure 1 is a view showing the practical application of our invention. Fig. 2 is a vertical sectional view of the same. Fig. 8 is a detail perspective view of the upper end ofthe tube, and Fig. 4 is a top view of the device. In constructing ya device in accordance 'With our invention we employ a metallic tube A of any suitable length and diameter, the interior of said tube being very smooth. Surrounding the tube A is a pipe B, through which steam or hot water is passed for the purpose of heating the tube A, said pipe B being coiled tightly around 'the tube, as Shown, and the tube is preferably constructed with spirallyarranged grooves O upon the exterior, into which the coils of the pipe it, thereby materially increasing the contact of the pipe with the tube, and consequently more efliciently heating the tube.

thoroughly dried The collars after being ironed and turned by hand are inserted in the upper end of the heated tube A and forced completely into the tube, and the second collar serves to force the first one still farther down, each succeeding collar serving to force the entire series down, and the lowermost collar will be forced out at the bottom of the tube andl is caught in a suitable receptacle, the time required to force a collar through the steam-heated tube being sufficient to thoroughly dry and shape the collar.

In order to enable the operator to force the collarsdown by hand below the top of the tube, we produce vertical notches D in the upper end of the tube, said notches being sufliciently large to permit the fingers to be inserted for the purpose of pressing down upon the top collar and forcing it below the top of the tube. A supporting-bracket E may be employed to support the tube, or the tube may be supported entirely by the coiled steam-pipe B.

A suitable valve B is placed in the pipe B, so that the passage of steam through the pipe can be controlled.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is*

l. A collar-Shaper, comprising a tube notched at the upper end and provided wit-h means for heating the same.

2. A collar-Shaper, comprising a tube having notches at its upper end, and a heatingpipe coiled around said tube.

3. A collar-Shaper, comprising a tube having a smooth interior, notched at the upper end and a grooved exterior and a heatingpipe coiled around the tube and fitting in the exterior grooves.

4. A collar-Shaper comprising an upwardly and downwardly open tube having a smooth interior surface and circumferentially grooved upon its outer face, a plurality of pipe-coils resting in said grooves and means for admitting a heated iiuid into said coils.
